The reality star, who's preparing for her nuptials to Kanye West on May 24, wore a tuxedo-style Balmain blazer over an Alexander McQueen top. She paired them with a long Lanvin skirt that featured a bustle and a train in the back.

"Honored to be at the USC Shoah Foundation event to support Armenian genocide testimonies," Kardashian, 33, posted via Instagram from the event. "I'm sitting next to the most inspiring 100 year old Armenian genocide survivor."

Earlier in the day, Kardashian took to Twitter to set the record straight about her wedding. "We are not filming our wedding for Keeping Up With The Kardashians," she tweeted, adding that she and West are not married yet and they have not released a guest list.
